SPECIFICATION forming part of Letters Patent No. 654,209, dated July 24,1900.

Application filedDecemner 3, 1898. serial No. 698,221. (No model.)

To aZZ whom, it may concern: 7

Be it known that I, ALMON WEIDMAN, a citizen of the United States,residing at Albany, in the county of Albany and State of New York, haveinvented new and useful Improvements in Ash-Sifters, of which thefollowing is a specification.

My invention relates to ash-sitters; and it consists in the novelconstruction and combinations of parts, as will be hereinafter fully setforth, and pointed out in the claims.

The objects of my invention are, first, to provide a reciprocatingsifting-box with end sifting-Webs in connection With the bottomsifting-web; second, to provide between a reciprocating sifting-box andan outer box a pair of trunnions having hearings in the latter and inthe upper ends of hangers pivoted to the former, and, third, to providewith the sifting-box and an outer box a pair of trunnions which areintegral with an adjustable bailhandle adapted to serve as a conveniencefor carrying and dumping the sifting-box.

The same letters of reference refer to similar parts throughout theseveral views in the accompanying drawings, forming a part of thisspecification, in which- Figure 1 is a plan of my improved ash-sifter.Fig. 2 is an elevation with parts broken away and parts in section andillustrating my improvements, and Fig. 3 is a section taken at line 1 inFig. 2.

In the drawings, A represents the outer box, which is the housing-box ofthe siftingbox. A is a circular-form bottom firmly secured to said outerbox by nails or screws (not shown) and having a central opening ofdimensions and form corresponding with the chamber of said box and alsohaving a downwardly-projected flange or rim adapted to hold with theupper end of a barrel on which this sifting device is to be placed foroperation.

13 is a cover for closing over the upper side of the outer box A forpreventing dust escaping from the sifter when being operated. This coveris shown to be pivoted to the outer box, yet it may be a loose cover, ifpreferred.

0 is the sifting-box, preferably of rectangular form and comprising theside pieces 0 c and end pieces 0' c and open above. These side pieces 0and end pieces 0 are preferably of wood the. former extended down fromtheir upper edges to the full depth of this sifting-box, while the endpieces a e have a less extension from their upper edges, downwardly, sothat their lower edges 0 are on a plane two inches, more or less, abovethat of the lower edges of the side pieces 0.

D is a sifting-web made of wire (1 and com= prising suitable meshes.This web is secured to the side pieces 0 c of the sifting-box bysuitable means, as heretofore practiced by the trade, and has its endportions D turned up against the ends of said side pieces and lap on thelower margin of the end pieces '0 c, as shown in Figs. 1 and 2, so thatthe ends of this siftingbox may have their upper portions solid andtheir lower portions of open-work construction for ready passage ofashes from within the box to without the same by the way of the ends ofthe box as well-as through the meshesin its horizontal bottom portion.

E E are hangers, which are pivoted by suitable pivots e 6, one at eachside, to the side piecesc c of the sifting box and about at the middleof length of the same and at points at a short distance above the loweredge of said side pieces. The upper ends of these hangers E are pivotedon suitable pivots e, which are suitably supported in bearings 6provided in the upper edge portions of the side pieces of the outer orhousing box A.

F is a bail-handle, which 'may be pivoted to the sides of theash-sifting box 0, as indicated by dotted lines, taken in connectionwith full lines of the bail-handle F, in Fig. 3, yet at present I preferto make this bail-handle integral with pivots 2, supported in bearings eand receiving the upper ends of the hangers E E, as shown in Fig. 3.With this form of bail-handle and its support in the bearings 6 so as tobe removable therefrom at will, and its pivotal connection withthehangers E E, this bail-handle operates as a convenient means for liftingthe sifting-box out from its housing-box, and also is made to serve assuitable trunnion-form pivots for oscillating the hangers, which arethemselves removable from the housing-box. Although the pivot ends e ofthe bail-handle from which the hangers are oscillated may be made tohave direct bearing on the bottoms of the bearings 6 made in the uppermargin of the side pieces serving as a convenient means for operatingthe sifting-box in a reciprocating manner.

By my above-described improvements the sifting-box is suspended freefrom contact with any parts liable to excessive friction when thesifting-boxis charged, while the ends of the sifting box allow the ashesthrown by its reciprocating movements against their open-work endportions to freely escape from said box and quickly relieve the coal andcinders from the ashes mixed with them. The bail-handle is made to havetwo added functions, in that it is made to serve as a means forsuspension of the hangers, which are pivoted to the sifting-box, and atthe same time it serves as trunnions for support of the suspendedsifting-box from the housing-box, while the pole-like handle secured tothe sifting-box coacts with the guidingslot for holding the former frombeing tilted in either direction while being operated, besides violentconcussions heretofore attending the reciprocating movements of thesifting-box within the housing-box and which operated to graduallyloosen parts of the sifter are wholly prevented, so that all parts ofthe sifter may be longer preserved in their normal good condition forbest service.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. The combination with ahousing-box and a reciprocatingsifting-boxwithin the former, and hangers pivoted by their lower ends tothe sides of the sifting-box, of the bail-handle F, having integral withit pivots e e, from which said hangers are oscillated, and bearings e 6provided in the upper margins of the side pieces of the housing-box andreceiving the extensions of said pivots e (2', sub-.

stantially as set forth.

2. The combination with the housing-box A, reciprocating sifting-box C,and siftingweb D forming the bottom and portions of the ends of saidsifting-box, of a bail-handle having integral with it pivots e e,hangers E E pivoted by their lower ends to the side pieces of saidsifting-box, and having their upper ends oscillating on said pivots e e,bearings e 6 provided in the side pieces of thehousing-box and receivingthe extended portions of said pivots e e, and the handle G secured tosaid sifting-box and guided by a slot pr0- vided in an end of saidhousing-box, substantially as set forth.
